So, I went AFK in my office (Head of Security) and was made a changeling during the time. I took my usual evolutions: paralysis & silence sting. My objectives were to absorb three genomes, kill the chemist, take the captain's antique laser, then escape on the shuttle alive.
After absorbing the wounded engineer in medbay I was walking through the halls with the HoP when wormholes came. I accidentally fell into one and went into space. I made multiple jumps, then landed on the solars. Then I dropped dead. It took multiple resurrections, but I got back in. After that, I ran around for a bit hunting Captain Jay Wright. Then the shuttle was called. I walk onto the bridge and cancel the shuttle, then drag over a locker and hide it in. Captain Wright comes back in and I pop out and fire my energy gun multiple times, then cuff him and absorb him. I take his ID, drag his corpse into his personal restroom, then take his antique laser.
The HoP Dave Hamman (who was a traitor) and I made an agreement that I would find his corpse in space and clone him. In return, he would get me the laser. Since I already had it, I just left his corpse to float in the void and moved on. The chemist had left the game and ran off to god knows where, so the admin who made me the changeling just axed that objective and left me with the other three.
I run to medbay, walk into CMO Luna Wood's office, drag her braindead person into a patient room, and absorb her. I had reached my quota, so I just walked to the shuttle and waited. While I was going there, I ran into Randall B Evans, the CE who had just joined. I walk up to him, start rambling about how the station had gone mad, then whispered "And I'm the cause" before getting him with a paralysis sting and cuffing him. He managed to get up and run after I put the cuffs on, so I stunned him with my gun, absorbed him, then tossed his corpse in a locker. From there, I just waited for the shuttle and left. I forgot how much fun being a changeling could be.
At the end, apparently the engineer in medbay was a changeling along with myself. Dave Hamman and Jay Wright were traitors.
